This invention relates to what I na be termed a suction comb and isparticu arly adapted for use in the cleamn of cows, horses' and otheranimals. The evice com '.5 prises a comb which is adapted to sleek theanimals coat and at the same time loosen any dirt or scuri which may beimbedded 1n the hair, the suction nozzle, which is comblned with thecomb, acting to carry the foreign L matter away immediately andtherebyprevent its resettling on the animal.

It will be understood that the suctlon nozzle is adapted to be coupledto any suitable form of vacuum' producing apparatus for i creating thedesired suction in the nozzle around the comb.

One object of the invention is to construct the comb in such a mannerthat loose hair will not become entangled in the comb and thereby clogthe nozzle.

Another object of the invention is to form the nozzle in twoseparatcpieces, comprising the nozzle proper and a hollow or tubular handletherefor, and so constructing these elements that the nozzle proper,'which is of wide expanse and is adapted for use in cleaning the readilyaccessible parts of the animal, may be quickly removed from the hollowhandle which on its end is provided with comb teeth and is adapted to beused alone in cleaning those parts of the animal which are not soreadily accessible.

Referring to the drawings:

Fig. 1 is a longitudinal sectional elevation of ,the device taken on theline 1-1, Fig. 2;

Fig. 2 is a transverse sectional elevation taken on the line 2 2, Fig.1;

Fig. 3 is an inverted plan view;

Fig. 4 is an end view of the tubular handle of the device; and

Figs. 5, 6, 7 and 8 illustrate alternate forms of the invention. p

The device comprises a suction nozzle 1, which consists of an elongatedsubstantially flat hollow body portion 2 which gradually increases inheight from its opposite ends toward its center where the said hollowbody portion is provided with a substantially cylindrical hollowextension 3, which projects from one side of the said body portion at anangle with respect to the general plane of the saidbody portion. erespective side walls 4 and 5 ofthe hollow body portion 1 are spacedapart to forman elongated mouth oropening 6 in which is located the comb7. j

The comb 7 comprises a`solid portion or back Swhich is located withinthe opening 6 of the body portion 2 and is spaced above andsubstantially parallel to the bottom edge 9 of thev said body portion12.Teeth 10 of the comb project from the back 8 of the comb to a pointbelow or outside the bottom edge 910i1 the body portion 2 of the suctionnozz e The comb 7 may be applied to the nozzle by slotting the end walls11, 11 of the body portion 2 as at 12 and placing the ends of the combin said slots, swaging the ends of the comb over the said end walls 11at each side of the slots, or by sweating, soldering, or welding thecomb in the slots, or by locating the comb in a suitable die and castingthe body portion 2 around the comb to hold vthe comb in place.

The metal at the base of spaces formed between adjacent teeth is beveledin both direct-ions from the central plane of the comb as indicated at13 presenting a knife edge to the jdirt and hair being drawn into thenozz e li have found by experimentation that this construction preventsloose hairs from piling up between the teeth and clogging the nozzle,the knife edge 14 preventing the hairs from balancingon Ithe comb withone end on oney side thereof and the other end on the opposite sidethereof, such as happens when the base of the spaces between the teethare permitted to remain flat and at right angles to the direction oftravel of the air moving into the nozzle.

Obviously for 'short haired animals the teeth 10 do not extend as farbelow the bottom edge 9 lof the nozzle as is Vthe case wherethe comb isto be used on long haired animals. Likewise the spacing of the teeth mayvary in accordance with the state of compactness of the hair ondifferent animals.

'By m king` the T c'ombsjf removablafcombs is slightly' tapered toreceive the externally tapered end 15 of a suitable hollow handle pgrtsof the animal the nozzle 1 is employed,l

ing frictionally held on the hollow handle 16 but for the places lessaccessible, such for example as the places where the limbs join thebody, the nozzle 1 may be removed and the toothed end of the hollowhandle emplo ed to comb and clean in such places,in whlch case thehollow handle functions as the nozzle. j

Placing the comb directly in the center-,of

the nozzle mouth or opening 6 and running the comb longitudinally of theopening with the walls 4 and 5 spaced relatively close to the comb oneach side thereof permits the dirt to be loosened by the comb andimmediately removed from the hair and does not allow the ,dirt to settleon another part ofthe animals bod Spacing the knife edges 14 inwardlyfrom the bottom edge 9 of the nozzle permits the teeth to thoroughlycomb the hair without the hair becoming entangledin the teeth by thesuction in the nozzle. If desired, the comb may be removably se cured inthe nozzle 1 in any suitable manner,

suchfor example as that illustrated in Fig.A

5, wherein the ends of the lcomb 7a extend beyond the end walls 11, 11as illustrated at 18, and a pin or other.y securing device 19 passedthrough the ends 18 ofthe combs resting in socketsl 20 form'edat` theintersection of the bead 21, whichfs formed -around the .rions existentconditions.

' mouthy of the lnozzl'e,j vcithj-the body portion having variousdegrees oflcoursenessgorteeth of various lengths,etc.,may-bereadilyplaced in the nozzle tomeet the requirements of -va-yIn Fig. 6, I have shown a comb 7b in which the teeth are curvedoutwardly, ina direction away from the handle of the nozzle, asillustrated at 10b, the ortion of the teeth extending beyond the p anew-w of the mouth of the nozzle being disposed substantially at an.

angle relative to the plane of ther mouth of the nozzle. This curvatureof the teeth obviates the possibilities of the teeth pressing into thehide when the device is pushed-rather `than pulled over the hide. Inpushing .the device over the hide,the curvature-of thev teeth 10bpresents the lower portion of the teeth at an acute anglelwithrespect'ftothe' h1de whereupon the teeth will readily ride maaienover the hide rather than having a tendency to dig into the hide. Inpulling the device over the hide the natural tendency is for the teethto move away from the hide, therefore, there is vno tendency for theteeth to dig into the hide. The operation of this form of the '1 deviceis smooth and` eicient even in the hands 'of the most inexperienced or`indiscreet'operator. v 't Obvlously the curvature of the teeth 10b may,be eliminated vand the portion of the teeth extending beyond the planewof the mouth yof the nozzle bent at an angle other than ninety degreeswith res ect to said plane as shown at 10c Fig. 7, wit equaleifectiveness.

In Figs. v7 and 8, I have shown a comb adapted especially for use withanimals which are shedding hair. In this form of the invention the teethof. the comb are spaced relatively far a art andthe bases of the acesbetween t e teeth are curved as at 20, t ereby presentin no shar cornersin which loose hair may co lect. A so these bases are beveled on oneside only as indicated at 130, and these bases are located but a slightdistance from the glane :v -w of the mouth of the nozzle, so t atvshould any loose hairs become entangled'in the teeth of the comb theymay be readily removed by merely removing the nozzle 1 from the handle16 and vrunning the end .of the handle across the comb, the suction inthe handle 16 thereby removing the loose hairs from the teeth of thecomb. l
